Did you duly educate her as to the privacy concessions she'll have to make to avoid targeted advertising?
Did you duly educate her that she already has a user profile being built within whatever apps and services you allow her to use?
There's surely a middle ground, but where we are ain't it.
Edit: I see you've already answered the similar reply. In that case, you're saying that non-targeted ads are stupid, but you're educating your children to input fake data. That doesn't compute...
Edit 2: First sentence should read "as a result of targeted advertising" rather than "to avoid targeted advertising". Sigh.
